' METAL-LID FASTENING.

Patented Sept. 12, 1911. Serial No. 603,536.

To all whom it may concern:

Be it known that I, CHARLES T. Woo TnN, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Metal-Lid Fastening, of which thefollowing is a specification.

My invention consists of a novel fastening for the lid of a metal can orother receptacle to the body thereof, the same embodying a lid which isprovided with projecting pieces of pliable material, and a body formedwith a bead on the exterior thereof, said bead being adapted to havesaid pieces engaged thereunder, thereby effectively looking or fasteningthe lid to the body.

It consists further of a novel manner of forming the head on the bodywhereby said tongues may be conveniently turned under said bead andthereby interlocked therewith.

For the purpose of explaining my invention, the accompanying drawingillustrates a satisfactory reduction of the same to practice, but theimportant instrumentalities thereof may be varied, and so it is to beunderstood that the invention is not limited to the specific arrangementand organization shown and describe Figure 1 represents a perspectiveView of the lid member of a can embodying my in vention. Fig. 2represents a vertical section of said lid member and portion of saidbody member, the former being in position on the latter and operativelyinterlocked therewith. Fig. 3 represents a side elevation of portions ofsaid lid and body members. Fig. 4 represents a vertical section of aportion of the body.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings :A designates the body of a can, and Bdesignates the lid thereof, both formed of metal. Projecting radiallyfrom the peripheral rim C of the lid B are the tongues D which are ofpliable nature, and in the present case integral with said rim.

E designates a bead which extends horizontally and circumferentiallyaround the body A near the upper end thereof and is formed on the lowerterminal of the rim F which circumscribes the upper portion of the bodyA and depends from the top edge thereof and is a continuity thereof, itbeing formed by bending the material of the body outwardly anddownwardly on itself against the adjacent portion G of the side of thebody, thus producing said rim F, and curling or outwardly bending thelower terminal of said rim producing said bead E the latter beingoutturned from said terminal, it being not-iced that the rim is closelyin contact with said portion G of the side of the body, so that when thelid is placed on the body its rim C is flat against the rim F of thebody, and thus the lid is not required to be made of increased diameterto permit the tongues D to engage the bead E as will be hereinafteraccomplished.

The operation is as follows :-The lid is placed on the body as usual insuch cases, and the tongues D riding downwardly on the rim F arepresented to the bead E and then bent rearwardly thereunder forming thecurls or channels H, which embrace said bead from below the innerterminal of the curls extending well under the bead toward the portion Gof the body and in a manner entering the space between the bottom of therim F and the adjacent portion G of the body, it being noticed that saidbottom is free or set out from said portion so as to permit the terminalof the curls to be turned into said space, whereby the tongues tightlyembrace the bead and the lid is thus most firmly connected with thebody, with a tight joint on the underside of the lid and the top of thebend J existing on the edge of the body caused by converting the topportion of the body into the rim F, it being noticed also that the meansemployed for producing the above results are simple, practical, andinexpensive.

When the can is to be opened, the curls H are bent outwardly, so as tobe released from the bead E when the lid is disconnected from the bodyand the can accordingly is opened. The lid may be reapplied to the bodyand the tongues engaged with the bead as before, and so the device isadapted for repeated use.

In order to cause the rim C to form a tight joint with the bead E, thelower portion of said rim is outturned forming the gutter K whichembraces the upper portion of said bead and is tightened thereagainst,it being prevented from upward disengagement by the tongues D which arecurved around and under the bead E and interlocked or connectedtherewith and consequently with the body of the can as has been stated.Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is

In a fastening for the lid and body of a receptacle of the characterstated, a body having a circumferential outturned depending bead on theside thereofand a lid having a depending rim with its lower portion out-10 turned forming a gutter and pliable tongues extending from theperiphery of the rim with their lower ends inwardly curled and adaptedto embrace the bead on the body.
